'I'AE NITED IMPROVEMENT IN WEATHER-STRIPS.

Specification forming part of Letters Patent No. 122,703, dated January16, 1872.

To all whom it may concern:

Be it known that I, HERMANN BUSSMANN, of Syracuse, in the county ofOnondaga and in the State of New York, have invented certain new anduseful Improvements in Weather- Strips; and do hereby declare that thefollowin g is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing making a part of thisspecification, in whichi Figure l is a front elevation of a doorinclosed at its lower edge by means of my improved device. Fig. 2 is aplan view of the lower edge of said door; and Fig. 3 is a verticalcross-section of the same.

Letters of like name and kind refer to like parts in each of thefigures.

My invention belongs to a class of devices designed for inclosing-thelower edge and outer side of a door, so as to prevent the passage ofrain and wind beneath the same; and it consists in the peculiarconstruction and operation of the device, substantially as and for thepurpose hereinafter specified.

In the annexed drawing, A represents a strip of metal or other suitablematerial secured rigidly upon and horizontally across the outer face ofa door, B, near the lower edge, and from thence projecting outward anddown ward at an angle of about thirty degrees from a vertical line.Extending downward and forward from the under side of the strip A is asecond strip, 0, having the transverse form shown in Fig. 3, with itslower edge about upon a line with the corresponding edge of the door,which strip is secured loosely upon the strip A by means of two or morescrews, D, that pass upward through suitable longitudinal slots, 0,formed withinsaid strip 0, by which means the latter is permitted tomove longitudinally upon or beneath said rigid strip A, and also to havea slight vertical motion of its outer end. Secured to or near thelongitudinal center of the strip 0, at its under side, is one end of aspiral spring, E, the opposite end of which is fastenedto a lug, F,attached to the door, by which means said strip is drawn toward thehinged edge of the door and re tained in the position shown in Fig. 3,except when said door is closed. A second spring, G, attached at one endto or upon the door, has its free end bearing against the lower edge ofthe strip C so as to raise the same to its highest position, except whendepressed by shutting said door. The device thus constructed andarranged has a length just equal to the distance between the verticalsides of the doorframe H, upon each of which sides is placed a stop, I,which corresponds in shape to the outer line of strips A and 0 when thelatter is closed downward, and is so placed as to receive the ends ofsaid strips when the door is closed and force the movable one to occupythe position named. If, now, the door he closed the inner end of themovable strip strikes against the corresponding jamb and is forcedendwise upon said door until the opposite end ofsaid strip passes withinits jamb,after which the stops I force the lower edge of said stripdownward upon the sill K so as to entirely close the opening between thesame and the door..

The advantage obtained by this construction of the weather-strip is thatby means of its longitudinal movement upon the door it is en abled toaccommodateitself to the varying positions of the same and its frame soas to fill the space between the jainbs more perfectly than wouldotherwise be possible; and while possessing this merit said device isneither more expensive norliable to derangement than those ordinarilyused.

Having thus fully set forth the nature and merits of my invention, whatI claim as new is The strips A and O, constructed as shown, and combinedwith each other, the springs E and Gfthe stops I, and the door B,substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand andseal.

HERMANN BUSSMANN. [L.s.]
